Flat Pack UGM - Universal Glow Marker

The Flat Pack 7.5" Long x 5.5" wide x .25" thick Universal Glow Markers (UGM’s) or Glow In The Bonded Crystals are perfect for marking all your gear making it easy to find in the dark. These are a super bright, long lasting, reusable glow panel that does not wear out. They do not use batteries, bulbs or electricity.

You can even read a book when using this as a light source and light up a 3 person tent.

They recharge quickly by absorbing light from any light source. The brighter the light source, the brighter they glow.

Their original use was as emergency markers, marking survival equipment onboard submarines. The Navy required them to be “non-powered, rugged, re-usable, and non-nuclear”. We use them everywhere including marking camp sites, hanging them from the inside door knobs at hotels to help us find our way out.

Finding and tagging your gear out of a dark cargo hold has never been easier.

Flat Pack UGM

It emits a lot of glow after taking it off from an artificial light source and then tapers off a few hours later. When it is left out in the sun it gives off a strong green glow when you take it to the shade, and probably lasts the entire night (I haven't tested it yet but I'll do it soon).

My gripe would probably be the overall durability of the pack itself, as it is encased in a somewhat thick clear plastic, unlike the ones that are coated in resin and shaped in bars which I also bought as gifts :)

Quick delivery by CC too.

Great when you really need it

This is basically a bunch of "pebbles" that all glow in the dark. If you put it in the sun for about 5 minutes or shine a strong flashlight on it, it is probably the brightest glow maker you'll ever see. They aren't kidding when they say it glows bright enough to be able to read a street sign! Might be good for kids who are afraid of the dark too.
